We have exactly what you need for an adapter to go from the 7-blade connector on your vehicle to the 7-round connector on your trailer:

- Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Nylon # PK12727
or
- Pollak Trailer Connector Adapter - 7-Blade Plug to 7-Pole Round Pin - Die-Cast Zinc # PK12728

The only difference between the two is that one has a nylon construction on the plug and the other is a die-cast zinc. I have added links to video reviews of both adapters for you to take a look at as well.

Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
